【问题描述】：

我正在尝试访问 SharePoint 网站中的列表，我正在使用具有现代体验的 Sharepoint 365。

我的问题是我上线超时错误

clientContext.ExecuteQuery();

我使用此链接作为参考： https://docs.microsoft.com/en-us/sharepoint/dev/sp-add-ins/complete-basic-operations-using-sharepoint-client-library-code#basic-operations-with-the-sharepoint-net-client-object-model

这是我的代码：

using (ClientContext clientContext = new ClientContext("https:siteurl"))

    SecureString passWord = new SecureString();

    foreach (char c in "mypwd".ToCharArray()) passWord.AppendChar(c);

    clientContext.Credentials = new SharePointOnlineCredentials("myuser", passWord);

    Web web = clientContext.Web;

    // Retrieve all lists from the server.
    // For each list, retrieve Title and Id.
    clientContext.Load(web.Lists,
                         lists => lists.Include(list => list.Title,
                                                list => list.Id));
           
    // Execute query.
    clientContext.ExecuteQuery();

    // Enumerate the web.Lists.
    foreach (List list in web.Lists)
    
        label1.Text = label1.Text + ", " + list.Title;
    

【问题讨论】：

这是一个大型数据集吗？

不，我有几个包含 2 个项目的列表

【参考方案1】：

在代码中添加clientContext.RequestTimeout = -1，下面的代码供大家参考。

using (ClientContext clientContext = new ClientContext("https:siteurl"))

    SecureString passWord = new SecureString();

    foreach (char c in "mypwd".ToCharArray()) passWord.AppendChar(c);

    clientContext.Credentials = new SharePointOnlineCredentials("myuser", passWord);   
    clientContext.RequestTimeout = -1;
    Web web = clientContext.Web;

    // Retrieve all lists from the server.
    // For each list, retrieve Title and Id.
    clientContext.Load(web.Lists,
                         lists => lists.Include(list => list.Title,
                                                list => list.Id));
           
    // Execute query.
    clientContext.ExecuteQuery();

    // Enumerate the web.Lists.
    foreach (List list in web.Lists)
    
        label1.Text = label1.Text + ", " + list.Title;
